Abstract: PURPOSE: A method for setting up a data link is provided to firstly execute an initial procedure to set up a link of an identical configuration in an AN(Access Network) and an LE(Local Exchange) and to then execute other procedures for data link setup, in case that either the AN or the LE interfaced by a V.5.2 protocol is shut down and re-operated. CONSTITUTION: An AN(20) transfers an SABME(Set Asynchronous Balanced Mode Extended), a message for data link setup, to an LE(10) through a primary link(S10). The LE determines the transmission of a UA(Unnumbered Acknowledge) message for the data link setup request according to an allocated active link. In other word, because the LE received the data link setup request through the primary link, while it sets up a secondary link as the active link, the LE does not transfer the UA message to the AN(S20). If there is no UA message from the LE, the AN transfers a request message to switch over a link configuration, which the LE has set up as the active link, to the LE(S30). The LE transfers a switch over command message to the AN, in response to the switch over request message(S40). The AN transfers a switch over acknowledge message to the LE so that the LE can set up the primary link as the active link(S50). If this link configuration switch over procedures are completed, the AN transfers the SABME to the LE through the primary link(S60). The LE transfers the UA message to the AN(S70).
